Tool holder assembly

Abstract

A tool holder assembly includes multiple bases and multiple pivots. Each base has a first pivotal portion formed axially thereto, a first passage defined through the first pivotal portion, and a second pivotal portion formed axially thereto. One tool extends through the first passage. One of multiple pivots extends through the two holes of the two extensions of one base and the first passage of another base, such that the bases are pivotable relative to each other.

What is claimed is: 
     
         1 . A tool holder assembly comprising:
 at least two bases pivotably connected to each other and each base having a first pivotal portion formed axially thereto, a first passage defined through the first pivotal portion, and a second pivotal portion formed axially thereto, the second pivotal portion having an open side, two extensions respectively extending from laterally from a top end and a bottom end of the second pivotal portion, each extension having a hole defined therethrough, and   one of multiple pivots extending through the two holes of the two extensions of one of the at least two bases and the first passage of another one of the at least two bases to pivotably connect the at least two bases, each of the at least two bases having one tool extending through the first passage thereof.   
     
     
         2 . The tool holder assembly as claimed in  claim 1 , wherein a first recessed area is defined in a top of the extension that extends from the top end of each of the at least two bases, the first recessed area communicates with the hole corresponding thereto, a first shoulder formed at a connection portion between the first recessed area and a periphery of the hole corresponding thereto, a second recessed area is defined in a bottom of the extension that extends from the bottom end of each of the at least two bases, the second recessed area communicates with the hole corresponding thereto, a second shoulder formed at a connection portion between the second recessed area and a periphery of the hole corresponding thereto, each pivot is a cylindrical member and has a second passage, a first flange and a second flange respectively extend radially from two ends of each pivot, the tool extends through the second passage, the pivot extends through the two holes of the two extensions of one of the at least two bases, and the first pivotal portion of another one of the at least two bases, the first flange is engaged with the first recessed area and has an engaging portion on an underside thereof, the engaging portion is rested on the first shoulder, the second flange is rested on the second shoulder, the pivot is restricted by the first and second shoulders, the engaging portion and the second flange so as not to be separated from the base corresponding thereto. 
     
     
         3 . The tool holder assembly as claimed in  claim 1 , wherein the second passage of each pivot includes a restriction portion extending from an inner periphery thereof so as to position the tool in the second passage. 
     
     
         4 . The tool holder assembly as claimed in  claim 1 , wherein the tool is a hexagonal wrench. 
     
     
         5 . The tool holder assembly as claimed in  claim 1 , wherein the pivot is integrally formed with the base corresponding thereto. 
     
     
         6 . The tool holder assembly as claimed in  claim 1 , wherein the at least two bases have different sizes, two respective inner diameters and two respective lengths of the first passages of the at least two bases are different from each other so as to receive the tools of different sizes. 
     
     
         7 . The tool holder assembly as claimed in  claim 1 , wherein the first recessed area of each of the at least two bases is a non-circular area, the first flange is a non-circular flange so as to be engaged with the first recessed area. 
     
     
         8 . The tool holder assembly as claimed in  claim 1 , wherein a number of the at least two bases is 3, 4, 5, 6, 7, 8, 9, 10 or 12.
